810135 ÷ 6 
Our goal is to divide 810135 by 6.

Step 1:
6 can be fit into 8 1 times, resulting in a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 6 from 8, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 6

Advancing to step 2:
6 goes into 21 3 times with a remainder of 3.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 18 from 21 and we're left with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 6

Step 3:
If we divide 30 by 6, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 135.0
Subtracting 30 from 30 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 6

Step 4:
The number 6 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 1350.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 6

Going ahead to step 5:
13 divided by 6 is 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 13502.0
If we take 12 away from 13, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 6

Advancing to step 6:
If we divide 15 by 6, we get 2 and a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 135022.0
If we subtract 12 from 15, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
The number 6 fits into 30 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 135022.5
The remainder is 0 after subtracting 30 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
6 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 135022.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
6 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 135022.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 135022.5, and the remainder is 0.0.
